Snowy white tundra swans breed in the Arctic. Young swans have fluffy gray feathers in their first winter. The tundra swan call is higher and more like that of a Canada goose. Tundra swans mate for life and pair up for nearly a year before breeding. They breed in solitary pairs spread out across the Arctic tundra. They can be nasty protectors and are able to fend off predators like foxes. They prefer to nest near wetlands containing pondweed. They line their large, stick nests with moss and grasses. Females lay about four eggs and incubate them for 32 days. These large birds feed by dipping their heads underwater to pluck aquatic plants, roots, and tubers. Their diet consists of mainly submerged plants and roots, but they will also eat some cereal grains, corn, and mollusks, which are a kind of shellfish. The majestic tundra swan is a strong swimmer and can take off from the water with a running start and beat their wings until airborne. Their flapping wings produce a sound that earned them the name „whistling swan.“ They migrate thousands of miles to enjoy a milder winter in North America’s Atlantic and Pacific coastlines, bays, and lakes. Twice a year, they fly 3,725 miles (6,000 kilometers) round-trip between the breeding and wintering locations.

Although native to Europe, earthworms are found throughout North America and western Asia. They do not live in deserts or regions where there is permafrost or permanent snow and ice. Typically only a few inches (7 or 8 centimeters) long, some members of this species have been known to grow to a snakelike 14 inches (35 centimeters). Earthworms‘ bodies are made up of ringlike segments called annuli. These segments are covered in setae, or small bristles, which the worm uses to move and burrow. These terrestrial worms typically dwell in soil and moist leaf litter. Their bodies are characterized by a „tube within a tube“ construction, with an outer muscular body wall surrounding a digestive tract that begins with the mouth in the first segment. As they burrow, they consume soil, extracting nutrients from decomposing organic matter like leaves and roots. Earthworms are vital to soil health and to plants growing in it because they transport nutrients and minerals from below to the surface via their waste. An earthworm can eat up to a third of its body weight in a day.

Giraffes grow about 4 feet (1.2 meters) in their first year of life. A newborn giraffe is about 6 feet (1.9 meters) tall at birth and weighs about 150 pounds (68 kilograms). Many young giraffes, called calves, die from lion attacks during their first year of life. Once a giraffe reaches adulthood its height is often enough to protect it from lions. Adult giraffes, however, must still be careful of lions when they are bending down to drink water or rest. Usually giraffes will drink or rest in shifts so that at least one giraffe is always on the lookout for approaching predators. The giraffes‘ height and excellent vision give them a wide view of the grasslands where they live, making it easy to spot predators from a distance. Some scientists believe that other animals—such as zebras, antelope, and wildebeests—often congregate near giraffes to take advantage of their ability to see danger from a distance. The giraffe could be considered the early warning system of the African grasslands.

Howler monkeys are the loudest of all monkeys. They call to let others know where their territory is, alerting them to stay away. The calls sound like a loud whooping bark or roar. After one group of howlers call, another group answers. Howler monkeys usually do this in the morning and at the end of the day. These monkeys live in Central and South America. At home in the forest, they hardly ever leave the treetops. They don’t move very far each day, feeding leisurely at the very top of the forest canopy. Howlers mainly eat leaves, as well as fruits, nuts, and flowers. Howler monkeys get almost all the water they need from the food they eat. One of the few times they can be spotted on the ground, however, is during very dry spells when they need to find extra water. Howler monkeys have prehensile tails, or tails that can grip. The monkeys use their tails as a fifth limb to grip branches. Mostly it uses its tail to help grip branches as it eats and moves around high in the trees. Each family group is generally made up of 15 to 20 howlers. The leader is usually an old male. The head and body of adult howler monkeys range from 22 to 36 inches (55.8 to 91.4 centimeters) long and their tail can add 23 to 36 inches (58.4 to 91.4 centimeters). Though most species are classified as least concern, the Yucatán Black is endangered.

Chipmunks are part of the squirrel family, and while they look similar to their bushy-tailed cousins, chipmunks are actually smaller, with alternating light and dark stripes along their cheeks and backs. There are 25 species of chipmunk, 24 of which live in North America. Chipmunks are excellent tree climbers and swimmers who live in a variety of habitats, including plains, mountains, forests, and deserts. Chipmunks like to live alone in holes or burrows called dens. Chipmunks hibernate in cold weather, which means they spend most of the winter sleeping in their dens. One chipmunk can gather up to 165 acorns in a day. In just two days, a chipmunk can collect enough food to last an entire winter, although chipmunks typically hoard much more food than necessary. Chipmunk young are born in late spring, and stay in the nest for up to six weeks. Female chipmunks have one or two litters per year, each with four or five babies. Chipmunks are 7.2 to 8.5 inches (18.5 to 21.6 centimeters) long including their tails, which can account for nearly half of their length.

Mosquitoes are known the world over for their itchy „bites.“ And they’re also known for spreading some of the world’s worst diseases, including malaria, yellow fever, encephalitis, and dengue. Only female mosquitoes actually „bite.“ They use their mouth, which looks like an upside-down funnel with the narrow end pointing down, to pierce their „victim“ and sip liquid. This liquid could be either blood (human or animal) or plant juices, depending on the mosquito species. Male mosquitoes feed solely on plant juices. Different species prefer the blood of particular animals. Some mosquitoes feed only on snakes, frogs, or other cold-blooded animals. Other mosquitoes prefer birds. Still others prefer cows, horses, and people. Like most insects, mosquitoes have two compound eyes, each of which contains thousands of six-sided lenses that point in all different directions and move independently. Mosquitoes can’t focus their eyes like people. Instead, their eyes stay open to help them detect quick movements. The mosquito’s wings beat about 1,000 times per second and create the insect’s telltale buzzing sound. The female’s wings create a higher-pitched tone than the male’s, helping it attract potential mates. Most female mosquitoes lay their eggs—up to 200 at a time, depending on the species—in water or near it, although not all species must hatch their eggs in water. Favorite places to lay eggs include any place that water pools, such as marshes and swamps, plus tree holes, discarded containers, and poorly maintained swimming pools. Transparent parts that cover the mosquito egg keep it from sinking. In warm weather, most eggs hatch within three days.

A rainbow-colored crustacean skitters along the ocean floor, adding a splash of brightness to the murky setting. The animal’s narrow, hard-shelled body sports orange, green, red, and blue hues. Known as the peacock mantis shrimp, this beautiful, seven-inch-long critter looks harmless. But the marine animal packs a punch—literally. SHRIMP SMACKDOWN Peacock mantis shrimp mostly live in shallow parts of the Indian and Pacific Oceans. The crustacean spends much of its time looking for crabs and mollusks to eat. When it finds a delicious-looking snack, the animal goes into full-on boxer mode. Springing out one of its club-like front claws, the animal delivers a swift punch to its prey. The punch is 50 times faster than the blink of an eye and strong enough to break glass! These shrimp also rely on their sparing moves to keep enemies away from burrows in the ocean floor that they use as shelters. Hovering at the opening of its burrow, a peacock mantis shrimp will strike at intruders that come too close. EYES ON THE PRIZE The crustacean has another eye-popping feature in addition to its strong punch. Its eyes—which protrude from its head and move independently—can see in two different directions at once. They can also detect colors that humans are unable to see. It’s easy to be floored by this animal’s cool traits! Watch a video of the peacock mantis shrimp. Text by Andrea Silen, NGS Staff
